PULPING-MACHINE.

To all 101 1-0772 it may concern:

Be "it known that I, HARRY V. Lown, a citizen of the United States,residing at Indianapolis, in the county of Marion and tate of Indiana,have invented a new and useful Pulping-Machine, of which the fol lowingis a specification. l

It is the object of my inventionto provide a pulping machineconstruction which can be easily opened so as to give access to all theinternal parts and thus facilitate cleaning and promote the maintenanceof sanitar conditions, which when in operation is e fective to producepulping throughout its entire circumference, and from which thedischarge of the refuse after pulping is obtained peripherally bycentrifugal force so as to minimize the danger of clogging and providean easier control of the discharge.

In carrying out these objects, I provide a pulping machine in which thepulping screen is made of two separate parts having hinge mountings sothat they may be opened to give access to the inside of the screen andto the working parts within the screen; and I provide a pulping screenabove as well as below the horizontal plane through the axis of thestructure, so that the juices and pulp may be forced through the screenthroughout its circumference; andI provide at the discharge end of thestructure one or more peripheral openings the size of which is suitablycontrolled, from which openi'ngsthe refuse after the pulping operationisdischarged by the action of centrifugal force.

The accompanying drawing illustrates my invention. a n

Y memberisannular, topermit the supplying preferably below the shaft 14;and on these two hinge rods arepivotally mounted the carrying frames 21oftwo semi-cylindrical screens'22. The frames are provided with anysuitable latching devices 23 for holding their upperedges togetherwhendesired, so

that the two semi-cylindrical screens will together form a completecylindrical screen inclosing the shaft lt and paddles 16 and close tothe inside surfaceof which the pad- .dles 16 travel when the shaft 14 isrotated.

By releasing the latches 23, the two semicylindrical screens may beswung apart abouttheir hinge mountings on the hinge rods 20,- asillustrated in 1, so as to give ready access to the inside surface ofthe screen andto the parts inclosed by the screen. The two: end membersare provided with annular shoulders 24:, upon which the curved end edgesof the screen-carrying frames 21 h ar when the screen is closed as shownin Fig 4(so as to provide substantially tight I joints between suchscreen-carrying frames and the end members. a

The endmember lQ at thedischarge end of the machine is provided with oneor more peripheral discharge openings 2. located between the end wall 26of such end member and an intermediate outwardly projecting "flange 27from which the annular flange which provides the shoulder 24 proiects.

These peripheral discharge openings 25 are conveniently locatedsubstantially opposite eachother. in about the horizontal plane of theshaft 14, and are provided with adjustablecurved gate valves 28 by whihthe sizes of such openings may be adjustedand either openingmaybecompletely closed. The

openings 25 preferably it are continued through outwardly projectingchutes, of which part of the walls are formed by continuations of theendlwall 26 and flange 27.

ing hinge rods 20 and supported in. any suitsupport a removable cover33, which retains the pulp and juice thrown out through the screen 22and guide such pulp and juice downward to the drain pan.

yIn operation, the two semi-cylindrical screen parts are closed to forma complete cylindrical screen, and the cover 33 is in place,asillustrated in Fig. 4-. The material to be Jul aed such as ve etablesor fruit is supplied 'to 'the interior. of the screen 22,

through any suitable devices or mechanism,

which may be simply the feed hopper .18

leading to the feed-opening 17. After this -mater1al reaches the insideof the cylindrical screen, the shaft 14 being in operation, suchmaterial is agitated by the moving paddles l6 and thrown outward therebyagainst 7 the inside surfaceof thecylindrical screen 22 tocause juiceand pulp from such material to be forced out through the screen. Thepaddles 16 travel sufliciently close to the inside surface' of thisscreen so that they also positively force pulp and juice from thematerial outward through the screen. The

pulp and juice are thus forced out through the screen throughout thecircumference thereof, and are caught by the cover and directeddownwardly thereby through the opening in ther'ectangular frame members32 into the drain pan 30, whence the juice and pulp are drawn offthrough the discharge opening-31. The refuse which is not I i5v .by thecentrifugal action produced by the forced outthrough the screen 22 worksdown toward the end member 12 at the discharge end of the machine, beingcontinuously held out against the inside periphery of the screen paddles'16.' When this refuse reaches the end member 12, itis thrown by thissame centrifugal force outward through the peripheral openings'25oreither of them, ac-

cord-ingBto whether one or both of them are open. y adjusting the gatevalves '28, the discharge of the refuse is controlled, so that suchdischarge is retarded to any extent necessary to produce the desiredqualities in the'refuse'and in the pulp and juice. By

9 closing the gates 28 to a greater extent, the discharge of therefus'eis more greatly retarded so that it 1s maintainedin the ma chinelonger and is drier when discharged,

jbecau sej more of the liquid and the softer matter is forced outwardthrough the screen 7 and caught ln the dram pan.

When the pulping operation is over, and
